I am not tied to Faenza. I will try the fix anyway. choosing Faenza was just part of my playing around. I will also try setting Ambiance and Radiance. I think ubuntu-mono-dark is what I once had active and what I like. Will check that after works. Thanks!

Et voila. The icq problem is gone! As I changed all USE flags at once I cannot tell which one made the difference... Going to persist them now.

Regarding the icon situation it doesn't matter which icon set and theme I use. The nautilus (and at some other spots) icons are missing. Also when slecting ubunto-mono-dark for example the icons for the indicators in the appmenue like battery, wireless/nm-applett, sound etc. do not change but stay like they were in the previous them which made a change. Mst of the time they look like Gnome-default. (so pretty ugly -sorry). I revert all Apperance settings back to default (with the accoridng buttons like "Use default". But no luck.

EDIT2: I've been too fast. pidgin (which was also not working) is now working. empathy still no luck. But I do not care. That's too much compiling for my precious SSD. I'll use pidgin! The icons are anyway of more importance.

EDIT3: Icon issue finally solved!!! I unmerged all icons-themes on tty with no X processes, did a deep world update newuse which failed on gnome-icons-theme-standard, due to an issue with gnome-base/librsvg. After a one-shot merge of gnome-base/librsvg it has gone through. At this point in time before firing up X I basically already knew that a remerge of gnome-base/librsvg only would have been enough probably... I remember that I've seen the same message (when running apps from console and in strace) that made the icon-theme merge fail (Error processing input file with to-pixdata: failed to load "./assets/dnd-counter.svg": Couldn't recognize the image file format for file)...

Great you got it sorted!
I'll try and mess with enabling some of those USE flags then and see if I can reliably reproduce the problem as time permits.

Hey! You can change them to whichever side you want by using System Settings > Unity Tweak Tool > Appearance - Window Controls > Layout: Alignment
This happens in real time and shouldn't require logging out of your Xsession.

shiznix, please help.
Frame rate performance became not so good as some month before.
this is for example http://ubuntuone.com/2H8ul6Xm8obyZy8swiUSwJ
Frames changed sharply, not smoothly, BUT in fool screen mode all is OK.
I guess the problem is in compiz (may be).
What i must to check?
Thank you

ps: my card is nvidia 660m

Perhaps your gfx rendering is running in software mode.
Doing the following should give you some info about that:

That seems OK, all running in hardware supported accelerated gfx mode.
Looked on launchpad.net for any reported bugs on the problem, it has definitely been a problem in the past specifically with Unity+Nvidia ( such as https://bugs.launchpad.net/ubuntu/+source/unity/+bug/988079 ) but nothing pops up recently...

Here are a couple of quick things to try:
1. Reset compiz using the command '/usr/bin/compiz.reset' as your desktop user within an Xsession
2. Get some more debug output from nux:

The log is written to your xsession logfile. I use GDM so for me it's ~/.cache/gdm/session.log
Also check ~/.xsession-errors and syslog files for any bad or strange messages.

Some other things to try might be to downgrade back to a lower nvidia driver version, or even try some of those 'workarounds' listed in that bug above if you get really desperate.
Yet another alternative is to try different nvidia driver packages, ie. x11-drivers/nvidia-drivers vs. x11-drivers/xf86-video-nouveau

Unfortunately I don't have any Nvidia hardware to test on anymore, but if I did then I'd try to reproduce the problem in native Ubuntu.
This would require a real Ubuntu installation, and not from within a VM so that gfx hardware acceleration can be tested.
Depends on how much trouble your willing to go with this, you might be able to get away with booting into a Ubuntu LiveUSB/CD/DVD to reproduce.

Only once it can be reproduced in the native Ubuntu would you have grounds for a bug report on launchpad.net (imo).

Sorry I couldn't be of more help but let us know how you get on, cheers!

Regarding performance, job-related I've a lot of dealings with nvidia-cards (on Windows). The focus of the 300 driver series are the new kepler-boards. Unfortunately this ends up in performance decreases for the old fermi (and older) boards. It would not surprise me, if the Linux drivers behave same.

The best driver for fermi boards is ~295.xx. Sadly this driver series is not maintained by nvidia any more, so it's not possible to use them with the current xserver-1.13 and newer.
So it can be, that you'll not get the old performance unless nvidia does it's homework or you get a keppler board.

I don't know what nvidia driver is used (recommend) at Ubuntu. If it's a 290 driver version, it's may good to check if they have some patches to get this version work with the current xserver.

Hi
Thank you for reply
I check perfomance on nvidia-drivers (310,313,319 from portage) - no profit
I execute /usr/bin/compiz.reset in tty mode - have big message (may be error? can' post it)
I debug unity - ~/.cache/gdm/session.log http://www.pasteall.org/42751
I create new user with default profile - no result.
No result(((

Indeed, /usr/bin/valac did not exist, just valac-0.{14,16,18,20}. I did ln -s /usr/bin/valac-0.20 /usr/bin/valac and it worked, but I don't know why it wasn't there in the first place. I have vala-0.20.1 installed.

It seems, the package needs vala-0.18 as dependency.

Can you paste the complete build log, please?

Fix committed to setup the needed VALA environment variables using vala.eclass
Safe and recommended you remove the /usr/bin/valac symlink now.

/usr/bin/compiz.reset needs to be run as your desktop user inside a desktop environment using an xterm (not a tty).
Thanks for the session.log, lots of info.

Some GTK errors there in your session.log that can occur with the gtk overlay scrollbar, so you can try and disable it.
Overlay scrollbar is disabled in System Settings > Unity Tweak Tool > Scrolling > Scrollbars > Legacy
You might need to log out of your Xsession and back in if this is to make any impact on window performance.

There also looks to be some errors in your ~/.nvidia-settings-rc file that may not be helping.

First of all I would like to say thank you for your job to have unity on Gentoo! I really appreciate what you guys are doing!

I would like to ask some help regarding the must have x11 drivers. As far as I can see to install unity on Gentoo requires vmware, nouveau and intel drivers. Is there a way not to force them to emerge? I had to install them and now I have to recompile my kernel due to intel driver. I'm sure I won't use any of them because I have a nice nvidia card.

Ok, the question is not valid anymore. I have Unity on my desktop. Nice! Thanks for your job again!

I would like to ask some help! After I restart my system the launcher (the fancy menu at left hand) and the taskbar (top of the page) do not appears. I haven't found anything in the logs. Can you give some suggestions about where can I find meaningful logs to figure out why this happened?

It sound you have to reset compiz. We had this topic a while ago. Please have a look at page 20, starting with the post of RussK from 20.05. 2013

I have checked and you were right I had to reset compiz. Now, it is working fine._________________- -

I would like to ask about network management in unity. I put together a system on my girlfriend's laptop because she is fed up with Ubuntu. But there is no nm-applet available on the tray - vertical menu. If I open the "Network" software then it says that my system is not compatible. If I open the Network Connections then I'm not able to add or change anything because everything is inactive.

My girlfriend is working on her laptop and she is moving everywhere and I really want her to suffer with scripts. I want her to use a good applet which helps her to find a wireless network and connect to it easily.

How is possible to solve it this issue?_________________- -
